Calabasas SLF Landfill - Agoura Hills, California Solid Waste Management Facility

Calabasas SLF is a landfill facility located at 5300 Lost Hills Road in Agoura Hills, Los Angeles County, California. Operated by the Sanitation Districts of Los Angeles County, the site has been in operation since 1961 and is expected to remain open until 2040. As a major solid waste management facility in the region, it handles municipal solid waste from surrounding communities. The facility operates under the regulatory framework of the US EPA, including RCRA Subtitle D for municipal solid waste landfills and Clean Air Act regulations for landfill gas management. California's stringent environmental standards further govern leachate control, groundwater monitoring, and methane emissions. The landfill likely employs gas collection systems to mitigate greenhouse gas emissions and comply with state and federal air quality rules. Calabasas SLF plays a critical role in Los Angeles County's waste management infrastructure, serving a densely populated urban area. Its long operational history and planned closure in 2040 reflect ongoing community service and environmental stewardship. The facility's proximity to residential areas necessitates robust odor, traffic, and leachate management practices to minimize local impacts.

Located in the Santa Monica Mountains region, the landfill operates in a semi-arid climate with seasonal rainfall that influences leachate generation. Groundwater protection is a key concern due to the underlying hydrogeology. Methane emissions from decomposing waste are managed through gas collection systems, which also help reduce odors and greenhouse gas contributions. The facility's proximity to urban areas requires careful traffic management and community engagement to address noise and air quality concerns.
